If you see any build up or dust on the air conditioner filter, it's time to clean it. If your central air filter shows no signs of grime buildup, you can use the hose attachment from your vacuum cleaner or use a handheld vacuum to remove any debris.
There are some key variables you will need to be able to keep your furnace filter going strong: Wash or vacuum the filter once a month. Many filters have a minimum efficiency value rating. The higher the MERV rating number, the more effective your filter will be.
Not every filter can be reused; HEPA filters and soft, pleated filters usually cannot be reused based on their design. If the material is made with something like fiberglass, it is pointless to reuse the filter, because of how it traps particles. The truth is, the more powerful air filters are usually disposable ones.
Yes you can but, blow it out from the inside of the air filter all the way around and it will work for at least another six months under normal conditions. Next time you should replace it with a good quality filter.
Immersion in Warm, Soapy Water – Where stubborn air-borne dirt is present, the filter may be dipped in a solution of warm water and mild detergent. Then simply rinse in clear water, let stand until completely dry and free of moisture, and return to service.
What happens if your HVAC filter is dirty? A dirty HVAC filter restricts airflow, which can lead to poor system efficiency, increased energy costs, and wear and tear on the unit.

Check the thermostat
You should check if it's been set to the correct temperature and also make sure it's set to “cool”. If the AC settings are not right, it won't turn on. You can also check if the batteries in the thermostat are fresh and replace them if needed.
You might wonder about the risks of running your AC without a filter, even temporarily. The simple answer is: not for long. Ideally, your AC should never operate without a filter for more than 6-8 hours. Going beyond this can negatively affect both your system's health and your home's air quality.
Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
If your AC isn't cooling your space as effectively as it once did, or if the airflow seems weaker, a dirty filter could be the culprit. Cleaning it could bring back your AC's cooling power.
Unkempt air filters may negatively affect indoor air quality by spreading pet dander, dust, and other allergens throughout your home. This may lead to irritated eyes, nose, and potentially breathing problems.
You can vacuum an air conditioning system using or without a vacuum pump. However, most homeowners prefer using the vacuum pump because it makes cleaning easy. A vacuum pump can help remove moisture from your air conditioning system, allowing the AC unit to function effectively.
Vacuum the filter
Use the brush attachment on your vacuum to gently clean the filter. This step is effective for removing loose dust and larger particles and is ideal for filters that aren't excessively dirty.
Some air filters — permanent and semipermanent models — can be cleaned as part of regular HVAC system maintenance and replaced for continuous use. A disposable air filter, however, doesn't work the same way. At regular intervals, you must remove it from the HVAC cabinet, throw it away, and install a fresh filter.
To fix an AC not blowing cool air, ensure the thermostat is set to "cool" mode and the temperature is set lower than the current room temperature. Inspect the air filter as a dirty filter can restrict airflow. Ensure the condenser coils are clean and free of debris. Make sure vents are open and unobstructed.
Check these issues when the unit won't kick on: Check the thermostat and adjust the settings if it isn't set to Cool and an appropriate temperature setting to call for cooling. Examine the house circuit breakers for the AC unit and reset any tripped breakers. Check the air filter and replace the filter if it's dirty.
While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it's fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.
Wash your HEPA filter with warm water and allow it to dry if your model specifically states that water cleaning is safe. You can also soak your filter in hot water if it is extremely dirty. Clean non-washable, permanent HEPA filters using a vacuum to remove dust and debris.
Vacuum the Interior
Carefully vacuuming the interior of the furnace picks up a lot of dirt and debris. You may even have dead insects and spider webs in there, too. A thorough vacuuming could remove a lot of the unwanted accumulations inside the furnace.
Cleaning the air filter not only does not improve, but also deteriorates its filtration properties. Only periodical replacement of the filter with a new one can provide efficient filtration of the air entering directly into the combustion chamber of the engine.
While there are a number of commercially available coil cleaning solutions on the market, air conditioner coils can be cleaned with a solution of a mild household detergent and water. The detergent and water mix is applied to the coil using a low-pressure sprayer.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
